Abstract

Настоящее изобретение предлагает моноклональные антитела, которые связываются со спайк-белком коронавируса ближневосточного респираторного синдрома (MERS-CoV), и к способам их применения. В различных вариантах осуществления по настоящему изобретению антитела являются полностью человеческими антителами, которые связываются со спайк-белком MERS-CoV. В некоторых вариантах осуществления антитела по настоящему изобретению применимы для подавления или нейтрализации активности MERS-CoV, обеспечивая тем самым средство для лечения или предупреждения инфекции MERS у людей. В некоторых вариантах осуществления настоящее изобретение предлагает комбинацию одного или нескольких антител, которые связываются со спайк-белком MERS-CoV, для применения в лечении инфекции MERS. В определенных вариантах осуществления одно или несколько антител связываются с отличающимися неконкурентными эпитопами, входящими в состав рецептор-связывающего домена спайк-белка MERS-CoV.The present invention provides monoclonal antibodies that bind to the spike-protein of the Middle Eastern respiratory syndrome coronavirus (MERS-CoV), and to methods for their use. In various embodiments of the present invention, the antibodies are fully human antibodies that bind to the MERS-CoV spike protein. In some embodiments, the antibodies of the present invention are useful for inhibiting or neutralizing the activity of MERS-CoV, thereby providing an agent for treating or preventing MERS infection in humans. In some embodiments, the present invention provides a combination of one or more antibodies that bind to the MERS-CoV spike protein for use in the treatment of MERS infection. In certain embodiments, one or more antibodies bind to different non-competitive epitopes that are part of the MERS-CoV spike protein receptor-binding domain.
